Asus Crosshair VIII 3101 Beta Bios out !

[karmal]

If it helps, I have a C8F and I am stable with my 4x8Gb 4000Mhz downclocked to 3800Mhz and bios 3101. To reach stability I had to change the dram and vdd voltages as per recommended suggestions from Ryzen DRAM Calculator, but nothing else.

what voltages did you use I tried the bios 2311 2702 3003 raising the vsoc and dram a bit without results but I also have 128 gb of ram

I have C8 Formula with 5950x and 4x16 gb de ram @3600 Mhz (F4-3600C16Q-64GTZNC). My Bios is 3003 and my system is default. My system is stable.

As I said, I followed religiously the recommended settings for my dram suggested by the Ryzen DRAM calculator: https://www.guru3d.com/files-details...alculator.html

First I used the freeware version of the Thaiphoon Burner to get the specifications for my DRAM and generate the DRAM report : http://www.softnology.biz/files.html

Then I imported the report into the DRAM calculator ( following these steps: https://www.reddit.com/r/Amd/comment...port_your_xmp/ ) which gave me the clocks to set in the bios, and in my case suggested to set the voltages like these:
SOC Voltage: 1.125
VDDG CCD Voltage: 1.05
VDDG IOD Voltage: 1.05
cLDO VDDP Voltage: 0.950
It also gave the exact termination voltages and similar settings.

Before these changes, I was getting sudden reboots while idling on windows, now it is stable since a couple days with bios 3101. I understand that we should not have to do this kind of tinkering to have the DRAM working as intended, but this may work for you too anyway.

3101 or something, still the same performance, but for now, the RAM works in 1900 FCLK and 3800 MHz D.O.C.P. I'll see for how long and report back.

i have tried in all ways at least 4 different bios and all recommended voltage settings but my ram 4 banks of 32 gb total 128 gb does not work at 3600 mhz .. now i try to scale to 3400 hz and see if I still have reboots in docp ... but I have the impression that I will have to stay 3200mhz or even 3000mhz

Excellent results on 3101 so far for the Crosshair VIII Formula, no compatibility issues, stable for 12+ hrs as of now.

I was getting "load VGA BIOS" errors with a 5950x and a 6900xt - all gone now.

Been running this on my Dark Hero w/ 5950X & 64GB (4x16) 3600MHz CL14-15-15-35 RAM for a few days with PBO and DOCP active and everything else stock.

Very solid so far.

i have 128gb at 3600mhz a hyper kit x 4 32gb banks on crosshair hero viiia 3600mhz i have random reboots how long should i make them work to have a stable system? I also tried 3400 mhz but the system is always unstable .. now I have tried them all

Hi,
i'm testing the new beta bios and i have to report the same problems/performances.
The following settings avoid whea errors and/or random system restarts:

FCLK=1866Mhz
MEM_LCK=3733Mhz
CPU_OFFSET_VOLTAGE = -0.025V
CPU_SOC_VOLTAGE= 1,025V
DRAM_VOLTAGE= 1,35V
VDDG_CCD= 0,95V
VDDG_IOD= 0,95V
CLDO_VDDP= 0,85V
1,8V_PLL=1,81V

this is my ram .. i tried 4 different bios also the last beta at 3600mhz in docp i restart this also happens at 3400mhz.. 5 bios came out within 2 months obviously there is something wrong with these motherboards
